使用 REST API 还原 Azure 虚拟机

项目
08/05/2024

使用 Azure 备份完成 Azure 虚拟机的备份后，可以从同一个备份副本还原整个 Azure 虚拟机，或者还原磁盘或文件。本文介绍如何使用 REST API 还原 Azure VM 或磁盘。

执行任何还原操作时，首先必须确定相关的恢复点。

选择恢复点

可以使用列出恢复点 REST API 列出备份项的可用恢复点。这是一个使用所有相关值执行的 GET 操作。

GET https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/protectionContainers/{containerName}/protectedItems/{protectedItemName}/recoveryPoints?api-version=2019-05-13

{containerName} 和 {protectedItemName} 是按此处所述构造的。 {fabricName} 为 Azure。

GET URI 包含所有必需的参数。无需额外提供请求正文。

响应

名称	Type	说明
200 正常	RecoveryPointResourceList	OK

示例响应

提交 GET URI 后，将返回 200 (OK) 响应。

    },
......

上述响应中的 {name} 字段标识了恢复点。

还原操作

选择相关还原点之后，请继续触发还原操作。

备份项目上的所有还原操作都使用相同的 POST API 执行。只有请求正文随还原方案而变化。

重要

此处提到了有关各种还原选项及其依赖项的所有详细信息。请在继续触发这些操作之前查看。

触发还原操作是 POST 请求。若要详细了解 API，请参阅“触发还原”REST API。

POST https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/protectionContainers/{containerName}/protectedItems/{protectedItemName}/recoveryPoints/{recoveryPointId}/restore?api-version=2019-05-13

{containerName} 和 {protectedItemName} 是按此处所述构造的。 {fabricName} 是“Azure”，{recoveryPointId} 是上述恢复点的 {name} 字段。

获取恢复点后，需要为相关还原方案构造请求正文。以下部分概述了每个方案的请求正文。

还原磁盘
替换磁盘
还原为新虚拟机

还原响应

触发任何还原操作都是异步操作。这意味着，此操作会创建另一个需要单独跟踪的操作。

它将返回两个响应：创建另一个操作时为 202（已接受），该操作完成时为 200（正常）。

名称	Type	说明
202 已接受		已接受

示例响应

提交用于触发磁盘还原的 POST URI 后，初始响应为 202 (Accepted) 以及 location 标头或 Azure-async-header。

  }
}

由于还原作业是长时间运行的操作，因此应该根据使用 REST API 监视作业文档中所述对其进行跟踪。

还原磁盘

如果需要自定义从备份数据创建 VM 的过程，只需将磁盘还原到所选的存储帐户，然后根据要求从这些磁盘创建 VM 即可。存储帐户应与恢复服务保管库位于同一区域，并且不应采用区域冗余。磁盘以及已备份 VM 的配置（“vmconfig.json”）将存储在给定的存储帐户中。如上文所述，下面提供适用于还原磁盘的相关请求正文。

创建请求正文

若要触发从 Azure VM 备份还原磁盘的操作，需在请求正文中包含以下组成部分。

名称	Type	说明
properties	IaaSVMRestoreRequest	RestoreRequestResourceProperties

有关请求正文的完整定义列表和其他详细信息，请参阅“触发还原”REST API 文档。

示例请求

以下请求正文定义触发磁盘还原所需的属性。

{
  "properties": {
    "objectType": "IaasVMRestoreRequest",
    "recoveryPointId": "20982486783671",
    "recoveryType": "RestoreDisks",
    "sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",
    "storageAccountId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Storage/storageAccounts/testAccount",
    "region": "chinaeast2",
    "createNewCloudService": false,
    "originalStorageAccountOption": false,
    "encryptionDetails": {
      "encryptionEnabled": false
    }
  }
}

有选择地还原磁盘

如果你是有选择地备份磁盘，恢复点摘要和详细响应中提供了当前已备份的磁盘列表。还可以有选择地还原磁盘，在此处提供了更多详细信息。若要有选择地还原备份磁盘列表中的磁盘，请从恢复点响应中找到磁盘的 LUN，并将 restoreDiskLunList 属性添加到以上请求正文中，如下所示。

{
    "properties": {
        "objectType": "IaasVMRestoreRequest",
        "recoveryPointId": "20982486783671",
        "recoveryType": "RestoreDisks",
        "sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",
        "storageAccountId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Storage/storageAccounts/testAccount",
        "region": "chinaeast2",
        "createNewCloudService": false,
        "originalStorageAccountOption": false,
        "encryptionDetails": {
          "encryptionEnabled": false
        },
        "restoreDiskLunList" : [0]
    }
}

按上文所述跟踪响应，并且长时间运行的作业完成后，磁盘以及已备份虚拟机的配置（“VMConfig.json”）将出现在给定的存储帐户中。

替换已备份虚拟机中的磁盘

还原磁盘从恢复点创建磁盘时，替换磁盘会将备份的 VM 上的当前磁盘替换从恢复点创建的磁盘。如上文所述，下面提供适用于替换磁盘的相关请求正文。

创建请求正文

若要触发从 Azure VM 备份替换磁盘的操作，需在请求正文中包含以下组成部分。

名称	Type	说明
properties	IaaSVMRestoreRequest	RestoreRequestResourceProperties

有关请求正文的完整定义列表和其他详细信息，请参阅“触发还原”REST API 文档。

示例请求

以下请求正文定义触发磁盘还原所需的属性。

{
    "properties": {
        "objectType": "IaasVMRestoreRequest",
        "recoveryPointId": "20982486783671",
        "recoveryType": "OriginalLocation",
        "sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",

        "region": "chinaeast2",
        "createNewCloudService": false,
        "originalStorageAccountOption": false,
        "affinityGroup": "",
        "diskEncryptionSetId": null,
        "subnetId": null,
        "targetDomainNameId": null,
        "targetResourceGroupId": null,
        "targetVirtualMachineId": null,
        "virtualNetworkId": null
     }
}

作为另一个虚拟机还原

如上文所述，以下请求正文定义触发虚拟机还原所需的属性。

{
  "properties": {
          "objectType":  "IaasVMRestoreRequest",
          "recoveryPointId": "348916168024334",
          "recoveryType": "AlternateLocation",
          "sourceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Compute/virtualMachines/testVM",
          "targetVirtualMachineId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/targetRG/providers/Microsoft.Compute/virtualmachines/targetVM",
          "targetResourceGroupId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/targetRG",
          "storageAccountId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/testRG/providers/Microsoft.Storage/storageAccounts/testingAccount",
          "virtualNetworkId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/targetRG/providers/Microsoft.Network/virtualNetworks/testNet",
          "subnetId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/targetRG/providers/Microsoft.Network/virtualNetworks/testNet/subnets/default",
          "region": "chinaeast2",
          "createNewCloudService": false,
          "originalStorageAccountOption": false,
          "encryptionDetails": {
            "encryptionEnabled": false
          }
     }
 }

应该根据上文所述的还原磁盘的相同方式处理响应。

跨区域还原

如果在用于保护 VM 的保管库上启用跨区域还原，则会将备份数据复制到次要区域。可使用备份数据来执行还原操作。若要使用 REST API 在次要区域触发还原操作，请执行以下步骤：

选择次要区域中的恢复点

可以使用“列出用于 CRR 的恢复点 REST API”列出次要区域中备份项目的可用恢复点。这是一个使用所有相关值执行的 GET 操作。

GET https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/protectionContainers/{containerName}/protectedItems/{protectedItemName}/recoveryPoints?api-version=2018-12-20

{containerName} 和 {protectedItemName} 是按此处所述构造的。 {fabricName} 为 Azure。

GET URI 包含所有必需的参数。不需要其他请求正文。

注意

要获取次要区域中的恢复点，请使用 API 版本 2018-12-20，如上例所示。

响应

名称	Type	说明
200 正常	RecoveryPointResourceList	OK

示例响应

提交 GET URI 后，将返回 200 (OK) 响应。

上述响应中的 {name} 字段标识了恢复点。

获取访问令牌

若要执行跨区域还原，需要访问令牌来为你的请求授权，以便能够访问次要区域中的复制还原点。若要获取访问令牌，请执行以下步骤：

步骤 1：

使用 AAD 属性 API 获取次要区域（以下示例中的 chinaeast2）的 AAD 属性：

GET https://management.chinacloudapi.cn/subscriptions/{subscriptionId}/providers/Microsoft.RecoveryServices/locations/chinaeast2/backupAadProperties?api-version=2018-12-20

    "servicePrincipalObjectId": "00000000-0000-0000-0000-000000000000"
  }
}

步骤 2：

使用获取访问令牌 API 为你的请求授权，以便访问次要区域中的复制还原点：

POST https://management.chinacloudapi.cn/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/protectionContainers/{containerName}/protectedItems/{protectedItemName}/recoveryPoints/{recoveryPointId}/accessToken?api-version=2018-12-20

对于请求正文，粘贴上一步中 AAD 属性 API 返回的响应内容。

{
  "properties": {
    "tenantId": "00000000-0000-0000-0000-000000000000",
    "audience": "https://RecoveryServices/IaasCoord/aadmgmt/wus",
    "servicePrincipalObjectId": "00000000-0000-0000-0000-000000000000"
  }
}

响应示例

返回的响应格式如下：

}

将磁盘还原到次要区域

使用跨区域还原触发器 API 将某个项还原到次要区域。

POST https://management.chinacloudapi.cn/subscriptions/{subscriptionId}/providers/Microsoft.RecoveryServices/locations/{azureRegion}/backupCrossRegionRestore?api-version=2018-12-20

请求正文应包含两个部分：

crossRegionRestoreAccessDetails：粘贴上一步中执行的“获取访问令牌 API”请求的响应的 properties 块，以填充请求正文的这一部分。
restoreRequest：要填充请求正文的 restoreRequest 段，需要传递之前获取的恢复点 ID、源 VM 的 Azure 资源管理器 (ARM) ID 以及要充当暂存位置的次要区域中的存储帐户详细信息若要执行磁盘还原，请将 RestoreDisks 指定为还原类型。

下面是将 VM 的磁盘还原到次要区域的示例请求正文：
